Implementations§

source§

impl Schnorrkel

source

pub fn new(context: &'static [u8]) -> Schnorrkel

Create a new algorithm with the specified context.

If the context is greater than or equal to 4 GB in size, this will panic.

Trait Implementations§

source§

impl Algorithm<Ristretto> for Schnorrkel

§

type Transcript = MerlinTranscript

The transcript format this algorithm uses. This likely should NOT be the IETF-compatible transcript included in this crate.
§

type Addendum = ()

Serializable addendum, used in algorithms requiring more data than just the nonces.
§

type Signature = Signature

The resulting type of the signatures this algorithm will produce.
source§

fn transcript(&mut self) -> &mut Self::Transcript

Obtain a mutable borrow of the underlying transcript.
source§

fn nonces(&self) -> Vec<Vec<<Ristretto as Ciphersuite>::G>>

Obtain the list of nonces to generate, as specified by the generators to create commitments against per-nonce. Read more
source§

fn preprocess_addendum<R: RngCore + CryptoRng>( &mut self, _: &mut R, _: &ThresholdKeys<Ristretto>, )

Generate an addendum to FROST“s preprocessing stage.
source§

fn read_addendum<R: Read>(&self, _: &mut R) -> Result<Self::Addendum>

Read an addendum from a reader.
source§

fn process_addendum( &mut self, _: &ThresholdView<Ristretto>, _: Participant, (): (), ) -> Result<(), FrostError>

Process the addendum for the specified participant. Guaranteed to be called in order.
source§

fn sign_share( &mut self, params: &ThresholdView<Ristretto>, nonce_sums: &[Vec<<Ristretto as Ciphersuite>::G>], nonces: Vec<Zeroizing<<Ristretto as Ciphersuite>::F>>, msg: &[u8], ) -> <Ristretto as Ciphersuite>::F

Sign a share with the given secret/nonce. The secret will already have been its lagrange coefficient applied so it is the necessary key share. The nonce will already have been processed into the combined form d + (e * p).
source§

fn verify( &self, group_key: <Ristretto as Ciphersuite>::G, nonces: &[Vec<<Ristretto as Ciphersuite>::G>], sum: <Ristretto as Ciphersuite>::F, ) -> Option<Self::Signature>

Verify a signature.
source§

fn verify_share( &self, verification_share: <Ristretto as Ciphersuite>::G, nonces: &[Vec<<Ristretto as Ciphersuite>::G>], share: <Ristretto as Ciphersuite>::F, ) -> Result<Vec<(<Ristretto as Ciphersuite>::F, <Ristretto as Ciphersuite>::G)>, ()>

Verify a specific share given as a response. This function should return a series of pairs whose products should sum to zero for a valid share. Any error raised is treated as the share being invalid.
